Frequently Asked Questions
Q: What stepper motor sizes is this driver module compatible with?
A: This stepper motor driver module is designed for small two-phase, four-wire stepper motors in the NEMA 20 and NEMA 28 form factors. It is ideal for lightweight CNC, 3D printing, robotics, and automated positioning applications that require compact, precise motor control.
Q: What microstepping options are available on this stepper motor driver?
A: The driver supports 8 selectable microstep subdivisions via onboard DIP switches: 1, 2, 4, 8, 16, 32, 64, and 128. Higher subdivision settings provide smoother, quieter motor motion and finer positional resolution, making this driver versatile for a wide range of motion-control applications.
Q: Does this driver module have overcurrent protection?
A: Yes. The module includes built-in overcurrent protection, thermal shutdown, and motor load open-circuit detection. These safeguards help protect both the driver and your connected stepper motor from damage in the event of a fault condition.
Q: What control signals does this stepper motor driver accept?
A: The driver accepts 3.3V–5V differential pulse (P+/P-) and direction (D+/D-) signals, with a supported pulse frequency range of 100Hz to 20KHz. It is compatible with most microcontrollers, PLCs, and CNC controller boards that output standard step/direction signals.
